Links to the right? You mean on my sidebar?

I take some text, highlight it, and use the hyperlink tool (the one that looks like chains locked together). Then I find the link I want to use and paste it into the box that opens up and hit +insert. Then I hit the HTML button (which opens up a new window) and copy the section that has the code for the link.

Open up the customize window and hit info, then paste it into the description!
